A .50 cal blast from the past! These 1968 U.S. Military Technical Manuals covered .50 cal gun systems of the time as well as the turrets that carried them. After they was printed, these manuals were thrown into storage until we recently rescued them. None have ever been used, but they still show plenty of marks from storage, including grease smudges. Guaranteed to smell like history! Don't miss adding one to your collection of military publications.
